The Honeywell R7847A1082 flame amplifier. 2 OR 3 SEC Flame FAILURE RESPONSE TIME. FOR USE W/C7012AC.
Overview
The R7847A1082 is a solid-state plug-in amplifier that senses flame via flame rods or compatible ultraviolet detectors. It provides an accurate flame failure response and integrates with safety control relay modules in burner systems.
Key Features
-
Flame Failure Response Time (FFRT): selectable 2.0 or 3.0 seconds
-
Flame Signal Measurement: 0.0 to 5.0 Vdc via test jacks for monitoring flame strength
-
Detection Compatibility: Use with rectifying flame rods (e.g. C7004, C7005, C7007, C7008, C7009, Q179) and suitable UV flame sensors
-
Relay Module Compatibility: Designed to plug into Honeywell 7800 and R7140 Series relay modules via a keyed edge connector
-
Color-Coded Label: Green label to indicate rectification-type amplifier for easy identification
-
Durable Operating Conditions: Wide temperature range and humidity rating
